Battery charger Linogy LINOGY universal AA/AAA charger — for AA and AAA rechargeable cells

Linogy universal AA/AAA charger is a compact charging station designed to recharge standard AA and AAA rechargeable cells used in household devices. The unit supports multiple cell chemistries and provides an organized workflow: discharged cells are placed in the charging compartment, the system charges each cell individually and then moves charged cells to a lower storage area for immediate reuse. The charger is suitable for regular home use and helps replace disposable batteries with rechargeable alternatives.

Advantages

The charger supports AA and AAA formats and charges each battery independently, which helps maintain consistent performance across a set and can extend cell life. It features automatic cell-type recognition and safety measures that prevent charging of non-rechargeable disposable batteries. The device includes an e-ink display that indicates the number of charged cells and environmental metrics, and its housing and packaging incorporate recycled materials to reduce environmental impact.

Suitable for

• Remote controls and TV accessories
• Toys and handheld gaming devices
• Flashlights and portable lighting
• Small household electronics (clocks, wireless mice, keyboards)
• Home backup of commonly used AA/AAA rechargeable cells

How to use

Place discharged AA or AAA rechargeable cells in the upper charging compartment and connect a USB-C 5 V / 3 A power source. The charger will automatically detect the cell type and begin charging each battery individually. When charging is complete, charged cells are transferred to the lower storage compartment where they remain ready for use. Avoid placing disposable (non-rechargeable) batteries in the unit; the charger is designed to block charging attempts for such cells.

Usage recommendations

For best results, use the charger with AA and AAA rechargeable cells of appropriate chemistry (Li-ion, NiMH, NiCd). Charge batteries at room temperature and follow manufacturer instructions for individual cells. Keep the USB-C input connected to a regulated 5 V/3 A power source and store charged batteries in the lower compartment to maintain an organized supply ready for devices.
